F. MOMBER STORAGE ROLL FOR FILMS Filed Deo. 28. 1934 IIIIIIIII l Fran/Z M0 mbar /nvenor Patented June 15, 1937 'r orties Appiication December 28, 1934, Serial No. r250,509 in Germany December 30, 1933 4 Claims.

My invention relates to a storage roll for lms and one of its objects is such a roll of films subdivided into lengths, such as are used, for example, in the Leica cameras and similar small cinematograph cameras.

The storage roll consists of a spool core made in known manner of wood, metal or artiiicial material. On this the individual, separate lengths of film, provided, if desired, at both ends with the necessary notches, are wound one over the other, there being between each wound length and the next following length a protective paper winding which need not be connected with the length of lm. The paper strip is not wound 3 together with the length of lm as is the case with known roll films, but is wrapped around the individual lengths after these have been Wound.

Thus the user obtains the length of nlm in its nal form Without having to cut the ends of the lm or to change the lm in any Way. A further advantage is that the storage roll remains ready for storage and use after removal of a length of film without any further operation and without any fresh packing.

Preferably the storage roll is made light-tight by providing the core with the known end flanges or by the known method of coloring the lateral surfaces oi the film winding with a non-actinic color, or by protecting the winding from lateral access of light by sticking to it a disc of paper or like material which is impermeable to light.

According to another modiiication the films are not wound on a core, but are disposed in 35 a ring of metal, cardboard or the like. The

single films disposed within one another are wound so that they exactly fit one within the other. The film rolls are provided on the outside and preferably also on the inside with a 40 protective paper. With such a package the single film lengths can be withdrawn beginning with the innermost film. The rolls may be provided with discs on the front surfaces to protect them from lateral access of light. In order to 45 avoid that the individual iilm rolls may fall out there can be applied a sticking plaster on the front surfaces of the roll.

(Cl. 20G-59) The rolls can also be packed in a light tight box, for instance, of sheet metal.

The invention will now be explained with reference to the accompanying drawing.

Fig. 1 shows a front View of a roll according to this invention. The films are wound on a core l of cardboard or the like.

Fig. 2 shows a plan view of the iilrn roll shown in Fig. l. On the core l there are wound the films 2 with interposition of a prctective paper 3.

Fig. 3 shows a front View of a modied i'llm roll. In this arrangement the individual rolls are disposed within the metal core i.

Fig. 4 shows a plan View of the roll shown in Fig. 3. Each individual iilm roll 2 is provided inside and outside with a protective paper strip 3. The individual rolls 2 are fitted one within the other inside the metal ring What I claim is: v

1. A storage roll comprising individual lengths of lm wound to separate rolls fitting within one another, a protective paper strip Wound between each individual length and around the last individual length so that after unwinding an individual length of film the roll is still complete in itself.

2. A storage roll comprising a cor'e and wound on this core individual lm lengths, a protective paper strip Wound between each individual length and around the last individual length so that after unwinding an individual length of lm the roll is still complete in itself.

3. A storage roll comprising a metal ring and disposed within said metal ring individual lengths of lm wound to separate rolls, a protective paper strip between said separate rolls and around the last roll so that after unwinding an individual length of lm the roll is still cornplete in itself.

4. A storage roll comprising a core provided with iianges and wound on this core between the flanges individual lm lengths, protective paper strips wound between the rolls of individual lm so that after unwinding an individual length of lm the roll is still complete in itself, vand a protective paper strip wound around the outermost film roll.
